IMPROVEMENT lN AUTOMATIC FANS.

Specification forming part of Letters Patent No. 208,715, dated October8, 1878; application filed March 7, 1878.

To all whom it may concern:

Be it known that I, FREnERIoK K. Counts, of Butler, in the county of DeKalb and State of Indiana, have invented a new and Improved FanningAttachment forBeds, of which the following is a specification:

In the accompanying drawings, Figure lrepresents an end elevation of abedstead with my improved fanning attachment. Fig. 2 is a sectional sideelevation of the same.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish for beds, sofas, &c., animproved attachment by which the person sleeping or resting thereon willbe fanned in a superior manner, and thereby a current of air suppliedsufiiciently to keep the bed cool and insure a more comfortable rest inhot weather.

The invention consists of a bed-cover or cloth that is hung to hooks atthe foot end of the bedstead and attached to fulcrumed crankarms at thehead end of the bedstead. The crank-arms are operated by crank-rodconnection from a suitable clock-train, so as to impart a fanning motionto the spread or cover.

In the drawing, A represents a bedstead or other support for resting thebody, and B a cloth or spread that is attached to fixed hooks to at thefoot end of the bedstead, and, at suitable height above the head of thesleeper, to outer hook-shaped ends of fulcrumed crankarms 0 at thehead-board of the bedstead. The opposite ends of the crank-arms G areconnected by intermediate links I) to the crankrod D of the clock-trainE, that is placed under or close to the bedstead. The action of theclock-train raises and lowers the cloth and produces a current of airsufficient to cool the bed and keep the sleeper comfortably cool in warmWeather. The raising and lowering of the cloth may be accomplishedeither at the foot or head end of the bedstead or in the middle, or bothends may be raised or lowered at the same time, as found mostconvenient. The clock-train is to be run with a governor, so as toproduce a noiseless motion of the same. It is to be made of such size asto run from six to eight hours continuously. The crank-arms are hung tofixed supports cl of the bedstead, the supports being made adj nstable,so that the fan attachment may be raised to any desired height,according to the position of the person on the bed, sofa, or othersupport. In this manner a simple and efl'ective device for fanning andcooling beds in summer season is obtained, that maybe readily detachedwhen not in use, and replaced when required.

Having thus described myinvention, I claim as new and desire to secureby Letters Patent 1. The combination, with a bedstead or other supportfor the body, of a fanning attachment consisting of a cover or spread,secured at one end and raised and lowered at the other end by fulcrumedcrank-arms and an actuating clock-train, substantially as and for thepurpose set forth.

2. The combination, with a bedstead or other support for the body, of acover or spread, attached at one end to fixed hooks of the bedstead andat the other end to fulcrumed reciprocating crank-arms, set in motion bya clocktrain, so as to produce a fanning action of the spread,substantially as set forth.
